Status of new FLR handling / necessary co-assignment of PCI devices

Status of new FLR handling / necessary co-assignment of PCI devices

[Carsten Schiers]

Hi,

came across the following, known symptom: my board (see below) has four PCI slots,
equiped with a VGA card (left in Dom0), a DVB-C card (put in pv DomU #1), and two
DVB-S cards (put in pv Domain #2) with Debian Xen 3.2-1.

When using latest unstable build, the famous need to co-assign VGA adapter with all
other PCI devices appears. 

Question: is that considered a feature (and then, why did it work before) or a bug 
(with some patches arround in the list) that's still not fixed for pv?

Thanks,
Carsten.
